Getting MoliPlayer on iPhone to use Serviio

I have the MoliPlayer app on my iPhone, and when I choose "nearby" in the app, Serviio doesn't come up. My Seviio console is running on a certain bound IP address, but when I input that address in MoliPlayer's "Add shared device?" option at Samba smb://, MoliPlayer asks me for a username and password. But my Serviio doesn't use a username and password. Any help? I've gotten my Serviio console to work on WDTV Live for a while now, so it's not on the Serviio end. Just seeing if someone can help me set up MoliPlayer. Thanks.
